Jet Fan
Installation
The component parts of the fan assembly, including
silencers, must be fully aligned before being bolted
together so that no stress is placed on the equipment.
After components are fully aligned, all bolts can be
tightened in an alternating pattern.
The examples shown below is installed using standard
mounting brackets. Before beginning installation,
reference the airflow direction as indicated by the
direction decal attached to the fan.
REMOVING FROM STORAGE
— As units are removed
from storage to be installed in their final location, they
should be protected and maintained in a similar fashion,
until the equipment goes into operation.
Prior to installing the unit and system components,
inspect the unit assembly to make sure it is in working
order.
1. Check all fasteners on the fan, propeller, motor base,
and accessories for tightness.
2. Rotate the fan propeller by hand and assure no parts
are rubbing.
